Having successfully transitioned my native host deployment of NXRM to run inside a docker container (see here), I decided to embark upon the same process for my IQ server.

My objective is to run IQ Server in a docker container, whilst retaining existing scan results and configuration established through deploying IQ on my native host machine. I also need to reference the same key-store and config.yml, thus ensuring a seamless transition from native to docker container deployment.

-v /native-host-install-dir/sonatype-work/clm-server:/sonatype-work
The docker image references /sonatype work. This volume mounts the location of the sonatype-work used on my native IQ installation with the docker image mount point.

-v /nxrm-native-host-install-dir/etc/ssl/:/etc/ssl
The docker image references /etc/ssl/keystore.jks when connecting using SSL. This volume mounts the location of the keystore used on my native NXRM installation with the docker image mount point.

-v /native-host-install-dir/:/etc/nexus-iq-server
The docker image references /etc/nexus-iq-server in order to find config.yml. This volume mounts the location of the native IQ installation with the docker image mount point.

-e JAVA_OPTS="-Ddw.sonatypeWork=/sonatype-work"
Having identified the native installation of config.yml to the docker container, I need to explicitly override the value of the sonatypeWork configuration parameter contained therein.

This demonstrates that the docker image that I will run is the one that I have cached in Nexus Repository Manager.

-v /nxrm-native-host-install-dir/etc/ssl/:/etc/ssl
The docker image references /etc/ssl/keystore.jks when connecting using SSL. This volume mounts the location of the keystore used on my native NXRM installation with the docker image mount point.

-v /native-host-install-dir/:/etc/nexus-iq-server
The docker image references /etc/nexus-iq-server in order to find config.yml. This volume mounts the location of the native IQ installation with the docker image mount point.

-e JAVA_OPTS="-Ddw.sonatypeWork=/sonatype-work"
Having identified the native installation of config.yml to the docker container, I need to explicitly override the value of the sonatypeWork configuration parameter contained therein.

It is probably worth mentioning that these middle three steps may not apply to everyone.

The main takeaway from these three is that the default docker image is set to use the config.yml stored in /etc/nexus-iq-server, and ignores the one in /opt/sonatype/nexus-iq-server/ along side the IQ Server jar file which is typically the location that admins coming from a local install are used to customizing.

A second takeaway is that the default configuration does not include SSL, and while you can override config.yml settings with environment variables, it is difficult or not-possible to add SSL in this way.

The default sonatypeWork folder in the docker image is in fact /sonatype-work. This differs from the sonatypeWork location from the zip bundle where it is set to a relative location meant to reside in the install directory where the zip is extracted. When using the same config.yml inside of the docker image, as described in the fourth item, you will need to reset this using a Java Option when starting the container. Alternatively, adjust your sonatype-work volume mapping to the relative location in the container.
